cervical spondylomyelopathy (CSM), normal pressure hydrocephalus (NPH), DESH (Disproportionately Enlarged Subarachnoid space Hydrocephalus)Abstract
The clinical presentation of cervical spondylomyelopathy (CSM) and normal pressure hydrocephalus (NPH) have considerable overlap, including gait disturbance and urinary incontinence. These similar symptomatologies cause problems in differential diagnosis. The hypothesized pathophysiology involves obstruction of cerebrospinal fluid drainage due to cervical spondylosis. In diagnostic aspect, there are reports of the relation between severity of CSM from magnetic resonance imaging (MRI) and disproportionately enlarged subarachnoid space hydrocephalus (DESH) presentation. Regarding diagnostic testing for NPH, tap test, is reported to have false negative in pre-operative CSM patients. In the treatment aspect, there is a report about cognitive improvement in post-operative spinal canal decompression in some of CSM patients. However, the relative pathophysiology of CSM and NPH requires additional research.
